Shen Jingzhe, a modern psychological profiler, penetrated the script of a female palace fighting drama called "Feng Ling Ling" and became a cannon fodder who was about to be buried in the beginning. But she has a terrifying ability - "perception of the rhythm of all things". By observing extremely subtle regular changes in the air (human micro-expressions + plant growth trajectories + sand table dust distribution), she can construct an extremely accurate "future probability model" in her mind, thereby making judgments that approximate predictions. She used this ability to frantically save her life in the harem, but what she didn't know was that this was a flashback fan world derived from ancient books. Everything she did would be recorded in history books and become a "slap reference template" for future heroines.
